Answer to Question 1

ANS: D
The RT has an important role in the collection of an appropriate specimen of expectorated spu-tum. Patients should be advised to rid the mouth of contaminating saliva, either by rinsing with water or by spitting, and then to expectorate a specimen from deep within the tracheobronchial tree into a collection container. Prompt transportation to the laboratory is essential and improves the diagnostic yield from culture.

Answer to Question 2

ANS: B
In routine sputum culture, the isolation of bacteria, such as S. pneumoniae and H. influenzae, must be interpreted within the context of the Gram stain because these organisms can colonize the oropharynx, and their presence in culture may not signify true lower respiratory tract infec-tion.
